这篇文章主要为大家详细介绍了java实现简单的webservice方式，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文实例为大家分享了java实现webservice方式的具体代码，供大家参考，具体内容如下
经过测试 jdk1.6.10以下会出现bug 建议使用10以上版本
1、定义接口
package org.enson.chan; import javax.jws.WebService;import javax.jws.soap.SOAPBinding; @WebService@SOAPBinding(style=SOAPBinding.Style.RPC)public interface IMyService { public int add(int a , int b); public int max(int a , int b);}
2、实现接口
package org.enson.chan;import javax.jws.WebService;@WebService(endpointInterface="org.enson.chan.IMyService")public class MyServiceImpl implements IMyService { public int add(int a, int b) { System.out.println(a+"+"+b+"="+(a+b)); return a+b; } public int max(int a, int b) { System.out.println("a与b比较大小，取大值"+((a>b)?a:b)); return (a>b)?a:b; }}
3、定义服务
package org.enson.chan; import javax.xml.ws.Endpoint; public class MyServer { public static void main(String[] args) { String address = "http://localhost:8090/ns"; Endpoint.publish(address, new MyServiceImpl()); }}
4、测试服务
package org.enson.chan;import java.net.MalformedURLException;import java.net.URL;import javax.xml.namespace.QName;import javax.xml.ws.Service;public class TestClient { public static void main(String[] args) { try { URL url = new URL("http://localhost:8090/ns?wsdl"); QName sname = new QName("http://chan.enson.org/", "MyServiceImplService"); //创建服务 Service service = Service.create(url,sname); //实现接口 IMyService ms = service.getPort(IMyService.class); System.out.println(ms.add(12,33)); //以上服务有问题，依然依赖于IMyServie接口 } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } }}
5、TestSoap
